摘要:
An axial alignment structure for a fluid pressure pump(100) includes: a first housing (1) made of a resin; and a second housing (2) made of a resin, in which a housing (H) is configured in a state where the first housing and the second housing are joined to each other by thermal welding at a welding position (WP), and a pump rotor (Pr) is accommodated in the housing, and the first housing and the second housing have an axial alignment mechanism that axially aligns the first housing and the second housing such that axes of the first and second housings coincide with each other at the time of joining of the first housing and and the second housing to each other by the thermal welding.
摘要:
A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

A hollow fiber membrane blood purifying device (1) including a cylindrical container (2), a hollow fiber membrane bundle (3), a potting resin fixing portion (4) embedding and fixing the hollow fiber membrane bundle 3 at each end (2a, 2b) of the cylindrical container (2), headers (5) having nozzles (6), and ports (7) further has the structure in which each header (5) and the cylindrical container (2) are welded in at least two regions over the circumference. The inside face of the header (5) is in contact with a potting resin fixing portion cut face (4S) that is formed by cutting an outer side portion of the potting resin fixing portion (4) in the length direction of the cylindrical container (2) than the end face of each end (2a, 2b) of the cylindrical container (2), and the potting resin fixing portion cut face (4S) is in a compressively deformed state.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Kreiselpumpenlaufrads (1) mit einer Grundplatte (2), welche mit Pumpenflügeln (4) einstückig ist und einer Deckscheibe (3), welche aus einem thermoplastischen Kunststoffmaterial besteht, wobei Anlagebereiche vorhanden sind, welche über eine Ultraschallanregung erhitzt und aufgeschmolzen werden und nach Erkalten eine innige stoffschlüssige Verbindung bilden. Aufgabe der Erfindung ist es bei einem Kreiselpumpenlaufrad (1) aus Grundplatte (2) und Deckscheibe (3) für Formstabilität bei den Einzelteilen und für eine einfache und sichere Vormontage, sowie eine feste mechanische Verbindung zu sorgen, wobei nur eine geringe Anregungsenergie erforderlich ist. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.
摘要:
To easily and reliably perform positioning of a guide member without being restricted by a demolding direction of an instrument panel. Side portions of a guide member mounting portion (7) of the instrument panel (1) include a panel side welding guide surface (21) integrally formed therewith. The panel side welding guide surface (21) is spaced apart from the back surface of the instrument panel (1). Side portions of the guide member (6) include a guide side welding guide surface (22) integrally formed with the guide member (6). The panel side welding guide surface (21) and the guide side welding guide surface (22) overlap each other. One of the guide side welding guide surface (22) and the panel side welding guide surface (21) includes a position regulating recess (23). The other of the guide side welding guide surface (22) and the panel side welding guide surface (21) includes a position regulating protrusion (24) that fits into the position regulating recess (23) during vibration welding.
